| *** | dne has quit IRC (Ping timeout: 260 seconds) | [00:04] |
| mnathani | up_the_irons: thanks. I just tested it and the mtu is definitely higher than 1500 but its not as high as the other vps. for instance, this ping works with 4000 bytes on both vps but only on kvr29 when I switch it to 8000 bytes
ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 8500 | [00:15] |
| up_the_irons | so 8500 doesn't work on kvr02? | [00:15] |
| mnathani | also, rsync fails, using my kvr02 vps, downloading from the backup server.
does not | [00:15] |
| up_the_irons | hmm.. weird
just checked all int's and they are 9k maybe it's host related. kvr02 is still a Jaunty node, and kvr29 is Lucid | [00:16] |
| mnathani | ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 4034 << that one works on kvr02
ping6 fe80::21b:21ff:fe93:3e08%eth1 -M do -s 4035 << that one does not not sure if those values have any significance | [00:17] |
| up_the_irons | not sure | [00:18] |
| mnathani | one of the successful pings: 4042 bytes from fe80::21b:21ff:fe93:3e08: icmp_seq=1 ttl=64 time=0.416 ms | [00:18] |
| hazardous | yall are insane
lol | [00:22] |
| up_the_irons | hazardous: i won't argue that ;)
kvr03 and kvr04 on the chopping block next week | [00:24] |
| hazardous | lol | [00:24] |
| mnathani | anyone seen something like this before: http://imgur.com/DMFrist | [00:31] |
| up_the_irons | http://support.arpnetworks.com/kb/main/ntp-servers
it's official | [00:35] |
| hazardous | are you dropping all ntp traffic at edge or something? | [00:45] |

| mnathani | up_the_irons: mercutio: if the ARP metal port was switched to trunk, would the OS have to be aware of, and support VLan tags? | [01:35] |
| acf_ | afaik yes
trunk == uses vlan tags | [01:36] |
| plett | Depending on which vendor's meaning of the word 'trunk' you are using, yes. I would expect the machine to need to be able to cope with 802.1q vlan tags | [01:37] |
| mnathani | Windows would not qualify in this regard, would it | [01:38] |
| plett | As something suitable for use on a server, no :)
Googling for "windows 802.1q" however, says that it is possible, it seems | [01:39] |
| mnathani | essentially, the OS will be performing some of the switching task? | [01:40] |
| mercutio | mnathani: yes | [01:41] |
| acf_ | it's like having two NICs afaik | [01:41] |
| mercutio | mnathani: don't worry it's easy
trunk is cisco terminology afaik | [01:41] |
| acf_ | yeah | [01:41] |
| plett | There are fancy ethernet cards which the OS can offload the vlan tagging to (and tcp checksumming etc), but they're not common. The OS would probably be handling the tags in software | [01:42] |
| mercutio | it's not really like having two nics, it's like having a subdivided nic
oh it's like two nics when using kvm virtual machine or such | [01:42] |
| acf_ | eth0.1
eth0.2 | [01:42] |
| mercutio | if you don't expose the root port to the vm, but instead the vlan's
i call my vlan's things like vlan1705 | [01:42] |
| plett | I call them things like "mgmt" or "diskvlan" | [01:43] |
| mercutio | basically on bsd you just do ifconfig vlan1705 vlandev em0 vlan 1705
and it will create an interface called vlan1705 over em0 plett: most ethernet cards can offload vlan but it doesn't make any real difference uhh even cheap realtek do vlan offload afaik broadcom and intel definitely do | [01:43] |
| plett | Ahh, I didn't know it was common these days. The last time I needed to know about ethernet card specifics, it was still a rare thing | [01:45] |
| mercutio | plett: maybe on 10/100 cards | [01:46] |
| plett | These days all I need to know is that the on-board cards on the servers we buy are good enough for what I need to do :) | [01:46] |
| mercutio | plett: do you use i350s?
i350s can slpit into multiple cards so you can pass a virtual machine a stub pci device, and it gets it's own queue and bypasses hypervisor | [01:47] |
| plett | Not specifically, but "buy intel" has always been a safe bet when choosing ethernet cards
That's interesting | [01:48] |
| mercutio | you need vt-d support on the motherboard though
i was going ot try it, but i don't haev any spare pci-e x4 or wider slots :( and yuo can't plug an x4 card into an x1 slot i've got no idea why | [01:49] |
| plett | So you could pass a 'raw' pci device in to a KVM guest and it would actually be tagged when it reaches the outside world
That would save any virtio overheads | [01:50] |
| mercutio | i dunno about the tagging
i wonder hwo that wroks i want to try it even more now but yeah it's more efficient it's called vmdq often http://www.intel.com/content/www/us/en/network-adapters/gigabit-network-adapters/io-acceleration-technology-vmdq.html | [01:51] |
| i should learn to condense my sentences :) | [01:57] | |

| CaZe | Wasn't there some gaming NIC that was supposed to reduce latency?
http://en.wikipedia.org/wiki/Killer_NIC | [11:26] |
| BryceBot | Killer NIC :: The Killer NIC (Network Interface Card), from Killer Gaming, is designed to circumvent the Microsoft Windows TCP/IP stack, and handle processing on the card via a dedicated network processor. Most standard network cards are host based, and make use of the primary CPU. The manufacturer claims that the Killer NIC is capable of reducing network latency and lag. The card was first introduced in 2006. Hardware and Models... | [11:27] |
| m0unds | they got bought out by atheros
the nic's performance was pretty well aligned with a good intel nic they had buggy drivers and software that accompanied the nic, and included weird stuff like host-based qos (qos for apps on a single machine) etc | [11:40] |
| ...... (idle for 25mn) | ||
| brycec | "bro this is totally going to reduce my gaming lag"
(It was marketed towards gamers, as I recall) | [12:06] |
| m0unds | yep
it's now an onboard option on some "gaming" motherboards | [12:08] |
| brycec | lol
"Anandtech noted that the people who would stand to gain the most benefit from the Killer NIC, the low-end users, would also be the ones least likely to pay $280 for a network card." | [12:10] |
| m0unds | hahahah | [12:12] |
| brycec | brycec would just pickup a gfx card for that price, or much less. | [12:12] |
| staticsafe | Intel NICs do the job | [12:13] |
| m0unds | yeah, when i replaced my motherboard, i had to find one that had an intel nic and not killer or realtek
that was harder than it should have been | [12:15] |

| mercutio | the new intel chips have lower latency than the older ones | [13:28] |
| m0unds | by what, .x number of ms? | [13:34] |
| ....... (idle for 30mn) | ||
| mercutio | it's about 2/3rd of normal latency i think
but even with default coalescing settings vs tuned ones | [14:04] |

| up_the_irons | mnathani: yes, your OS would need to support VLANs. But, fortunately, they all do. | [16:06] |

i saw a thing about the ps2 dev team finding a server-side cause of bad hitreg that impacts 20+% of players | [17:03] |
| staticsafe | yeah | [17:04] |
| m0unds | hitreg has been horrrrrrrible for a few months now
my ping to connery is less than 60, and i regularly end up having whole magazines fail to register a single hit, only to die to one huge damage impulse | [17:05] |

| brycec | I've come to hate PlanetSide2 for no other reason than causing me to wonder who's still using+developing the PlayStation2. | [18:11] |
| staticsafe | LOL | [18:12] |
| brycec | Haven't had this issue with any other game either.
Makes me wonder how, with as many games released as there are, only PlanetSide2 stomps over another popular abbreviation | [18:15] |
| m0unds | it's developed by sony too | [18:20] |
| staticsafe | Waterson 48 - 43
damn | [18:21] |
| mercutio | wow up_the_irons
did you check your own servers? i know it's not open to the world, but would be curious if it happening none the less. | [18:24] |
| m0unds | wow, 300+gbps ddos against hong kong's online voting systems yesterday
guess i missed that | [18:31] |
| brycec | @wa time in hong kong | [18:34] |
| BryceBot | current time in Hong Kong;9:34:24 am HKT -> Saturday, June 21, 2014;1:34:24 am GMT -> Saturday June 21, 2014 | [18:34] |
| brycec | m0unds: it's because it hasn't happened yet. | [18:34] |
| m0unds | AAAAAAHHHHH
yesterday, 'murica time i managed to get someone scheduled to come look at my air conditioner on monday | [18:34] |
| mercutio | m0unds: i thought it blew up? | [18:36] |
| m0unds | compressor surely did | [18:36] |
| brycec | Hence why it needs repair/looking at | [18:36] |
| mercutio | oh right
i forget that it's not like an appliance that it brekas and you just get a new one | [18:36] |
| m0unds | hahaha, yeah | [18:36] |
| mercutio | wel li suppose some people repair fridges. | [18:37] |
| m0unds | well, this is a 4ton (48kbtu) unit | [18:37] |
| mercutio | and they're the most similar appliance
oh | [18:37] |
| brycec | Smaller AC units are more like appliances | [18:37] |
| m0unds | yeah
this cools a whole 2300sq ft dwelling, sans garage | [18:37] |
| mercutio | i hate air conditioning myself
but i don't live in a desert. | [18:37] |
| brycec | But big, house-cooling units are big. Too big to be a simple swap out. | [18:37] |
| m0unds | also unholy expensive when they break | [18:38] |
| mercutio | warranty? | [18:38] |
| m0unds | negative, 8 years old | [18:38] |
| mercutio | damn
good luck :) | [18:38] |
| brycec | "normal" warranties are against defects, not "wear" | [18:38] |
| m0unds | haha, thanks | [18:38] |
| brycec | Have fun, m0unds :) | [18:38] |
| m0unds | yeah, newer units have 10 year warranties if you get them svc'd yearly | [18:39] |
| mercutio | which costs more than getting a new one after 8 years i imagine | [18:39] |
| m0unds | hmmm
nah haha $200/yr x 8 years vs $8000+ for a new unit | [18:39] |
| mercutio | $8000?
wow that's way more expensive than a heat pump | [18:39] |
| m0unds | yeah, it's old enough to use the phased out barely in production refrigerant
which is ~$120/lb | [18:40] |
| mercutio | and is expensive to run?
can you chaneg to the new coolant? refrigerant 10+ year old fridges cost way moer to run | [18:40] |
| m0unds | you can, but you lose ~10-15% efficiency and run the risk of further damage | [18:41] |
| mercutio | so i assume it similar
really? | [18:41] |
| m0unds | yeah, because there's no way to guarantee you've evac'd all of the oil and stuff out | [18:41] |
| mercutio | there's two common ones now | [18:41] |
| m0unds | and the oil type used for one type of refrigerant isn't the same as what's used with the other | [18:41] |
| mercutio | r134a is one? | [18:41] |
| m0unds | in smaller units, like cars and fridges | [18:42] |
| mercutio | oh right
so it's different | [18:42] |
| m0unds | this is R-22 (old) and R-410a (new) | [18:42] |
| mercutio | r22 was in fridges? | [18:42] |
| m0unds | no idea
it's in my air conditioning system hahaha | [18:42] |
| mercutio | oh r12 was i think | [18:42] |
| m0unds | yeah, and old cars
my refrigerator is 134a iirc it's a couple years old hah, that's a ridiculous number of dead TR | [18:42] |
| mercutio | my fridge uses r600a | [18:44] |

| staticsafe | dat save by waterson | [19:06] |
| m0unds | yeah
i hate the octagon | [19:13] |
| mercutio | blow it up then? (jk) | [19:16] |
| m0unds | wish i could | [19:16] |
| mercutio | you should be careful about saying stuff like that
someone got into mega trouble by saying something about wanting to blow up in airport after his plane was severely delayed on twitter and itw as taken out of context etc. | [19:17] |
| m0unds | because the NSA might misconstrue saying i want to blow up a fictional facility in a video game as intent to commit terrorist acts? | [19:17] |
| mercutio | oh?
oh is that fictional? there's a oplitical place in this country with that name so i thought it may be in other places too well it's the city centre of one of the citys here http://www.bbc.com/news/uk-england-18607798 ahh this is what iw as thinking of | [19:17] |
| m0unds | http://i307.photobucket.com/albums/nn320/vulgarman/map%20stuff/PS2/octagon.jpg | [19:19] |
| mercutio | ahh
why is it upside down? | [19:20] |
| m0unds | couldn't tell you | [19:20] |
